Landmark: FMC Technologies' First Ethernet Next Generation Control System

Tyrihans is next-generation control system containing a new Ethernet function that allows simple connection to our own or third-party equipment. It also supports data communication and control within the network. The field will have raw seawater injection with pumps integrated into our system.

The project embraces two structures – Tyrihans South, an oil field with a gas cap, and Tyrihans North. The latter is a gas and condensate discovery with a thin oil zone.

FMC Technologies delivered 13 subsea trees and five template structures with manifolds. The agreement also included production control systems and umbilicals and workover systems for well interventions. The Tyrihans structures were developed with five seabed templates tied back to the StatoilHydro-operated Kristin platform. A 43-kilometer pipeline carry the wellstream to the Kristin platform.

The project was technologically challenging, since the new ISO standard calls for even tougher safety integrity levels on all equipment.

Tyrihans came on stream in 2009, and represents one of the biggest development projects on the Norwegian continental shelf (NCS) in coming years.
